Not quite sure how I got to that particular Intel website page. I had done many Google searches. My laptop information:
Lenovo Thinkpad model W510 (probably purchased late 2010)
The machine type is 4318CTO

Laptop has one USB 3.0 port on rear and two USB 2.0 on side of case.

I think I probably got to the Intel web page by using this page and searching on Renesas USB 3.0. I see from the dropdown menu that Desktop Boards is a choice, but nothing labeled "Laptops".

I also just saw that Intel has a free analysis tool to see what drivers might be needed for your computer on the search page which I am running now, but I also see that whatever they provide is generic and that the OEM might have modified things specifically for your computer model so they suggest always getting drivers etc. from OEM and not from Intel website. So don't think this will provide any useful information.

Thank, as far as I know what Lenovo means by machine types is different variations of the same laptop model e.g. how many Ram slots, etc. I can assure that I have only one USB 3.0 slot at back, and two USB 2.0 slots on side.

I have used the Lenovo Support links that you show; that is where it indicates that the driver 1.1.19.0 dated 1/22/2010 is up to date, even though Renesas/NEC has a later one that I installed yesterday. I see now with that same Renesas update that the firmware was updated to version 3025 BUT this was not done from the Lenovo website.

Perhaps?? I need to download the "same" firmware from Lenovo website as Lenovo might have some modification to it for their own laptops. Any suggestion on this? I am just speculating, and as I wrote before I know quite a bit about software use, but not much about hardware, so that is why I will defer to you experts on the forum.

Ok Lite machine type is a bit like PART No. with Toshibas as you need that for ordering specific parts for machines made in different areas or global sites.

It may follow that is what is needed for the Lenovo you have (and unlike you I am not software intensive) - a very specific driver or firmware for that machine. So I would be tempted to do just what you say and go with the Lenovo website stuff. Having said that I also think one has to be careful with the firmware stuff.
The fact that your machine only has the one 3.0 has got me wondering now if I have got even the right site.
The best I can find from my end is the whole ball game for Windows 7 for that model laptop and I selected all types too -Lenovo Support - Drivers & Software (US)? - am not real sure of which is the stuff you need now.

All in all things have got to be so convoluted now it makes more difficult to track down the gear one wants.

Thanks, yes convoluted matches my experience. So it seems like using the Lenovo firmware might make sense?

You did find, I believe, the right website area. I had done that previously and simply worked through the web page choices (which I can not re-create right now), but was something like
Choose W series laptops
then W510 then machine type of 4318 and finally CTO

I am using Windows 7 Pro 64-bit, and choose from the final drop down Windows 7 Pro, and also tried
Windows 7 64-bit. As far as I can tell they give the same result for the USB 3.0 firmware.

I am going to wait for either you or @Boozad to confirm that I should use the Lenovo website firmware. If so, I assume that it will simply replace the Renesas firmware which was part of the update yesterday. Your post did express some concern about firmware updates, so I have some hesitancy about proceeding - don't want to take on much risk of making things worse than they currently are. (Perhaps along with convoluted this is a corollary to "if isn't broken don't fix it" --- If it is only slightly broken and inconvenient, think twice about fixing it as it might work and it just might make it worse.)

Firstly, apologies for the delay lite1, it's been a hectic day. Right, quick recap now I'm sitting at home with a bit of peace and quiet.

Your BSOD reported the Renesas/NEC driver continually crashing, you updated the driver (and firmware) to the Renesas version and they installed without hitch. The USB 3.0 port works fine, as it should. I have a feeling that the Renesas controller only controls your USB 3.0 port and not the USB 2.0 ports and we're looking to try to fix the thing that isn't broken instead of the thing that is broken. Now, you also mentioned that the USB 2.0 ports and the USB 3.0 ports are running the same driver, please verify that for me mate as I can't find where I read it for the life of me.
I think the USB 2.0 ports are native to the motherboard so would require a different driver, the Renesas being a third party device has it's own dedicated driver. If the USB 2.0 ports somehow have the Renesas drivers installed instead of the ones they need (how that would happen I have no idea) it could well explain the ports not working and the BSODs.

If you don't mind amusing me, could you post a screenshot of Device Manager (View devices by connection) and expand your USB root hubs. See if you have something along the lines of this, but in place of the eXtensible Host Controller you may have Renesas/NEC.

I'm looking around the drivers for your machine now to see if anything shakes loose.

@Boozad Thank you so much. Yes it does seem like forum is having me fix USB 3.0 which isn't broken. Your summary of where we are at seems accurate. Screen shot is attached, as well as one showing the driver for USB 3.0 and for USB 2.0.

As written previously:
1) After running Renesas ".exe" file yesterday several things were updated including firmware. This also resulted in the addition of two entries in Device Manager for USB 2.0 and I do not recall a similar NEC USB 2.0 entry ever having been there.

2) I have indicated that a mouse, or thumb drive does work on the USB 2.0 port, and even though Western Digital 500GB ext. hard drive has its own power brick, it does not work. So my hypothesis is that amongst other problems the USB 2.0 ports are no longer getting correct power.

3) My work around from late last night: I re-attached the Lenovo port replicator that I usually use, but only use to connect mouse, printer, scanner, ext. keyboard and this was into USB 2.0 where I always put it. I then attached one of the WD HDs to the Lenovo port replicator and the WD showed up in Windows Explorer so I could off load some of my backups and other vital files.

I hope the detail and clearer picture will help you diagnose and then help me. Again, thanks so much.
